Aus dem Datassheet:

"IO-Warrior can act as an IIC master with about
100kbit/sec data rate (actual throughput is about
750bytes/sec). Multi-Master mode is not supported
by IO-Warrior, it has to be the only master on the
IIC.
Since the IIC bus in IO-Warrior is software driven
it does not have as stable a clock timing as
hardware IIC masters have. Make sure that the
devices you drive with IO-Warrior don't have a
problem with some clock jitter.
The following pins get reassigned"

Im SDK enthalten ist eine Dll, über die du aus so ziemlich jeder Programmiersprache auf den IO-Warrior zugreifen kannst.
